I have broadband via Slingshot (ADSL2) and since the last couple of weeks I noticed that my Broadband was getting slow for a while and then it picked up again. I had a look and noticed that  I got lots of attacks (see below).
I contacted Slingshot but the say they can't do anything about it.
I have a static IP address so turning modem off and on doesn't help.

Anyone out there who has bright ideas or suggestions?

Speed problems caused by DOS attacks on Slingshot, as seen by our router.
The table below shows where the attacks come from.
